since using angle sum property
180=angle 1+2+3
180-130=2+3
50=2+3
ii) assumption technique
let angle to be found =x
other angles as y and z
a) using angle sum ppty
x+y+z=180
y+z=130
but if sum of the whole angles (2and 3) is 50
then how can their bisectors sum be 130
b)similarly
therefore (c)
180=angle 1+2+3
180-130=2+3
50=2+3
